Data Zone
The site was identified as internationally important for bird conservation in 1998 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| White-winged Flufftail Sarothrura ayresi | CR | non-breeding (-) | present | A1 |
| Cape Vulture Gyps coprotheres | VU | non-breeding (-) | present | A1 |
| Black Harrier Circus maurus | EN | resident (-) | present | A1 |
| Bush Blackcap Sylvia nigricapillus | VU | resident (1998) | present | A1 |
| Buff-streaked Chat Campicoloides bifasciatus | LC | resident (1998) | present | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2013) is shown below.

| Grassland | good (>90%) | moderate (70–90%) | moderate |

| Invasive and other problematic species and genes | happening now | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | high |
| Biological resource use | likely in short term (<4 years) | most of population/area (50–90%) | moderate decline (10–30% over 3 generations) | high |

| Pollution | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Residential and commercial development | happening now | most of population/area (50–90%) | no or slight decline (<1% over 3 generations) | low |
| Human intrusions and disturbance | happening now | most of population/area (50–90%) | no or slight decline (<1% over 3 generations) | low |

|---|---|---|---|
| Designation | Planning | Action | Result |
| Whole area (>90%) covered by appropriate conservation designation | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | high |
